ZIC1 · rs78155705

What the study found

Who was studied 33,992 European ancestry individuals; replicated in 14,727 European ancestry individuals, 2,943 individuals.

The effect Each copy of the T allele shifted the measure 31.1 lower (95% confidence interval 23.54-38.6); p = 6 × 10−16.

How common The T allele had a frequency of about 9% in the people studied.

Where it sits Chromosome 3, band 3q24 — inside ZIC1.

What each result means

C/C No copy of the version the research linked to Cortical surface area. This is the starting point the study compared everyone against.
C/T One copy of the version the research linked to Cortical surface area. That is a smaller link than two copies.
T/T Two copies of the version the research linked to Cortical surface area. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs78155705

What is rs78155705?

rs78155705 is a single position in the genome, in or near the ZIC1 gene. Published research associates it with cortical surface area. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs78155705 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs78155705 come from?

GWAS Catalog, Science (New York, N.Y.) 2020, PMID:32193296. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
